`Letters Patent No. 113,620, dated April 11, 1871.

IMPRovrgMEl-ur IN A'uToMATic FANS.

The Schedule referred to in these Letters Patent and maldng part of thesame.

I, GEORGE O. Bo'vnY, of Cincinnati, Hamilton county, Ohio, have inventeda new and useful Automatic Fan, of which the following is aspecification.

.Ndtew'c mul Objects of the Invention. This invention relates to animproved form of selfacting fan, for attachment to a bedstead or tothe'v ceiling of an apartment, or other convenient object.

General. Descrtpt'ion with Reffnencetok the Drawing.

Figure 1 is a side elevation of a bedstead to whose head-board afanembodying my invention' is attached. i

Figure 2 is atop view of the head-board and fan, showing the lateral adjustability of the latter.

Figure 3 is a vertical section, showing the adjnsta-V I ble-bracket andthe propelling mechanism lin position on the head-board.

Figure 4 is a representation of my brake for arresting or retarding atwill the rotation of the fan.

Figure 5 represents my invention applied to the b edf Y otherandsmallerweight acts to keep Vthe cord at the proper stretch and causesit to hug the d'rum.

The gearing F is so'proportioned as to rotate the uppermost spindle ors'haft G at a much greater velocity than that 4of the drum C.

The shaft G protrdes through the head-board ,and is connected 'by agimbal or other universal joint, H,

with a shaft, I, that is journaled within the hollow` trough-like beam Jof a crane or L-formed bracket, Whose vertical portion, consisting of atube, K, is journaled in eyes L, that project from the front of thehead-board.'

The outer end of the shaft I has a bevel-wheel, M, that gears with.another bevel-wheel N upon a shaft, O, that journals in the end ofthebeam J, whence it depends vertically in the manner represented.

Two arms p p', projecting from the shaft O, may be provided with rollersI P,which, revolving upon a suitable plane or track, j, on thetop of thebeam J, may serve to support the shaft O and its appendauts, and toreduce thefriction to a minimum.

Attached by thumb-screw Q to the shaft O, at any desired height thereonis the frame R,.which supports two or more arms S S' of my fan proper.My preferred-form for'these arms' is as represented, viz: a horizon -alportion, s, which rests in the frame R, and having a perpendicularportion, s', that terminates in another horizontal portion, s", to whichare attached pendants T T, of mnslin, silk, feathers, or other suitablematerial.

The lperpi-zndicular portions may be tubular, as shown in'fig. 6, so asto permit of the horizontal part s of the arm turning therein so as tobe set at diiierent angles, as indicated by the dotted lines.

The object of this adjustment is to cause the-pendants T to offer agreater or lesser obstruction to the air and thereby servelto regulatethe speed of the fan.

The fan may be entirely stopped or its speed checked by means of labrake, U, which is operated by a cord, u, which passes down through thetubular portion K of the supporting-frame or crane.

' The crane may be swung from side, so as to permit of the bed beingmade, by the cords V V', as shown in iig; 2. f A

. i Claims.

I claim as my invention- 1. The combination of the rotary-fan R S T,shaft O, adj ustable-braclret J, gearing F, cord D, and weights E E', as4and for the purposes specied.

' 2. The combination vof the adjustable-bracket J, shafts I O, androtary-fanIt S T, substantially as set forth.

3. The combination of the brake U u with the rotary-fan It S T and itsshafts I` 0, substantially as described. y

In testimony of which invention I hereunto set my hand.

GEORGE O. BOVEY.
